Taiyuan Iron and Steel (Group) Co., Ltd. rolling production line reducer equipment case-China Weigao Biography

Taiyuan Iron and Steel (Group) Co., Ltd. (TISCO for short, TISCO for short) was founded in 1934 and is located in Taiyuan, the Longcheng by the Fen River.


Taiyuan Iron and Steel Co., Ltd. is a large-scale steel conglomerate integrating iron ore mining and steel production, processing, distribution and trading. It is also a global leader in the stainless steel industry, with an annual output of 12 million tons of steel (including 4.5 million tons of stainless steel).


TISCO leads development with innovation. Relying on scientific and technological innovation platforms such as the national technology center and the state key laboratory of advanced stainless steel materials, TISCO has formed a high-efficiency, energy-saving and long-life product cluster mainly consisting of stainless steel, cold-rolled silicon steel, and high-strength steel series. It is used in key fields and emerging industries such as petroleum, chemical industry, shipbuilding, container, railway, automobile, urban light rail, large power station, "Shenzhou" series spacecraft, and more than 20 dual-phase steel, heat-resistant steel, steel for railway industry, axle steel, etc. The domestic market share of this variety is the first, and more than 30 varieties fill the domestic gap and replace imports.


TISCO adheres to green development and advocates economical, environmentally friendly, civilized, and low-carbon production and lifestyle. It has successfully implemented dry quenching, coal humidity control, coke oven gas desulfurization and acid production, sintering flue gas desulfurization and denitrification, and blast furnace gas. Circulating power generation, blast furnace gas residual pressure power generation, saturated steam power generation, steel slag treatment, membrane industrial water treatment, urban domestic sewage treatment, acid regeneration and other energy-saving and environmental protection projects, the main energy-saving and environmental protection indicators are leading in the industry.


Taigang insists on reform and opening up and accelerates transformation and development. Construct resource guarantee bases and steel extension processing bases, and build an internationally competitive upstream and downstream industrial chain; develop new materials, engineering technology, financial services, international trade and other related diversified industries to form new profit growth points; promote international operations, It maintains stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, Britain, Japan, South Korea, and Australia, and maintains the largest export volume of stainless steel in China.


TISCO successively won the "China Industry Award", "Nomination Award of the First Chinese Government Quality Award", "National Quality Award", "National Advanced Unit of Circular Economy", "National Top Ten Independent Innovation", "National Technological Innovation Demonstration Enterprise", "National Enterprise with the Most Social Responsibility", "National Model Enterprise with Harmonious Labor Relations", "National Advanced Unit for Corporate Culture Construction", "National Model Unit for Greening" and other honorary titles.


Facing the future, TISCO will insist on strengthening its main business, extending development, diversified development, green development, and harmonious development, building the world's most competitive stainless steel company and becoming a world-class large-scale enterprise group.

DBY two-stage transmission conical cylindrical gear reducer


 The conical cylindrical gear reducer (hereinafter referred to as the reducer) is used for transmission devices in which the input shaft and the output shaft are arranged in a vertical direction. Mainly used in belt conveyors and various transportation machinery, but also in the transmission mechanism of various general machinery such as coal, metallurgy, mining, chemical industry, building materials, light industry, petroleum and so on.


1. The use, performance characteristics and model marking of the reducer


1.1 Purpose

The conical cylindrical gear reducer (hereinafter referred to as the reducer) is used for transmission devices in which the input shaft and the output shaft are arranged in a vertical direction. Mainly used in belt conveyors and various transportation machinery, but also in the transmission mechanism of various general machinery such as coal, metallurgy, mining, chemical industry, building materials, light industry, petroleum and so on.


1.2 Performance characteristics

High carrying capacity, low noise, small size, light weight, high efficiency and long service life.


1.3 Parameter range

DBY, DBYK, and DBZ reducers each have 12 specifications, and the nominal center distance is: 160, 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560mm. Each specification has 5 transmissions. Compared with (8, 10, 11.2, 12.5, 14) two rotation directions, four assembly types, respectively, make up 240 kinds of reducers.


There are 15 specifications for DCY, DCYK, and DCZ reducers. The nominal center distance is: 160, 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560, 630, 710, 800mm; each Each specification has 11 transmission ratios (16, 18, 20, 22.4, 25, 28, 31.5, 35.5, 40, 45, 50), two rotation directions, four assembly types, and 660 types of reducers.


This series of reducers can meet the power requirements of TD and DX belt conveyors and other transportation machinery in the working range of 0.8-6.5m/s belt speed.


1.4 Structure

Lubrication of reducer: Under normal circumstances, gears and bearings of reducer are lubricated by splashing oil pool and cooled naturally. Only when the working equilibrium temperature of the reducer exceeds the specified value, or the carrying power exceeds the thermal power PG1, the oil pool with cooling pipe is used for lubrication.


1.5 Model and marking

The model of the reducer is composed of type code, nominal center distance a (center distance of the final stage), nominal transmission ratio, assembly type code, and input shaft rotation direction code.


D-belt conveyor group code, B-two-stage transmission, C-three-stage transmission, Y-hardened gear, Z-medium hardened gear, K-output shaft is a hollow shaft.

Nominal center distance: expressed by actual numbers, the unit is mm

Transmission ratio: expressed by the nominal transmission ratio.

Assembly type: indicated by Roman numerals I, II, III, IV.

The direction of rotation of the input shaft: When looking at the direction of the input shaft, S is clockwise and N is counterclockwise.


Markup example:

The nominal center distance is 280mm, the nominal transmission ratio is 10, the assembly type is Type III, and the input shaft is clockwise rotating. The mark of the three-stage transmission reducer is: reducer DBY280-10-III S
