5 Typical project of lime kiln

(1)600t/d lime kiln project of Shougang Qiangang
       General situation: it was put into production in January 2010 with its yearly active lime production of 210,000 tons, it is the first 600t/d shaft kiln independently developed and designed in China.
       Technical characteristics: The kiln body structure of 600t/d shaft kiln is independently developed and the following advanced technologies are adopted such as parallel-flow calcine process, rotary distribution, heat recovery of cooling air and heat exchange of offgas, negative pressure operation, lime discharging by supporting board, heating-up of kiln with material, structure of bearing ring, addition of cooling beam for kiln shell, optimization of refractory structure for arch bridge and optimization of structure for combustion chamber, rational determination of annular space, reduction of wall effect and vertical process layout, etc. A completely independent design is realized.

(2)Shougang Jingtang 500t/d×4 lime shaft kiln
      General situation: Four 500t/d shaft kilns were set up totally. Three of the four shaft kilns produce 496,800 tons of active lime per year and one of them produces 165,600 tons of lightly fired dolomite per year. The project was built up in two stages. In the first stage, two shaft kilns were put into operation in June, 2009 and in the second stage, two shaft kilns were put into production in February, 2010.
      Technical characteristics: Short flow process and simple process arrangement; Thermal process system of shaft kiln is suitable for production of small-sized lime; Structure of kiln proper is optimized, advanced internal structure and refractory design are adopted; All-automation control system for the shaft kiln proper system; Deep-processing process of lime.

(3)Jingang 600t/d lime shaft kiln
      General situation: One 600t/d shaft kiln was set up and it produces 210,000 tons of lime per year. It was put into operation in December, 2013.
      Technical characteristics: Structure of kiln proper is optimized, advanced internal structure and refractory design are adopted. Control system is fully automatic and all indexes reach the advanced level of domestic equipment in China. The project wins the third prize of the Excellent Engineering Design in the Metallurgical Industry.

(4)2x500t gas combustion vertical lime kiln project for Jingang Shunsheng
      General situation: Two 500t/d gas combustion vertical lime kilns were set up totally and the project is with 330,000t/a lime production. It was put into operation in May, 2017.
      Technical characteristics: Many practical new techniques were adopted, such as large scale air cooling centre combined type burner, Japanese well type side burner, combustion air gas double-preheater, and so on. Low calorific value BFG was used as fuel. Raw material with 20~40mm particle size could be treated. Vertical kiln has simple structure and there is no shaped brick in refractory material. Material distribution at kiln top adopts the coordination of the idle screw distributor and the multitubular material seal distributor.

6 Typical project of steel slag treatment

(1)Shougang Qiangang secondary treatment production line of slag
      General situation: It was put into production in December, 2006 with its treatment capacity of 1,200,000t/a.

(2)General contracting project of secondary treatment production line of slag for Jianbang Iron & Steel Company, Shanxi
      
General situation: It was put into production in July, 2014 with its treatment capacity of 500,000t/a.

7 Projects on energy-saving and environmental protection

(1)Cold hardened pellet project of Rigang converter dedusting ash
      General situation: Its treatment capacity of converter dedusting ash is 200,000t/a~250,000t/a, and its treatment capacity of ferroalloy powder is 9000t/a.
      Technical characteristics: The first converter dry dedusting ash extruding ball production line in China, and a patent for innovation was obtained. Cold hardened pellet technology is used to realize high efficient recycle of primary dedusting ash of converter. Suction/discharge truck or pneumatic conveying is used for the reception of steelmaking dedusting ash to reduce transfer and flying dust in room. Pan mill is used for material blending to realize quick blending and reduce the consumption of binder. Tail gas of lime kiln is used for pellet drying to save energy and reduce consumption. Low running cost, and production cost is reduced by 200RMB/t pellet compared with sinter.

(2)Magang slag pot grating plate project
      General situation: Grating plate output per year is 6000 sets.
      Technical characteristics: 1) Raw material for slag pot grating plate consists of steel slag (size <35mm), refractory (size <35mm), cement and steel bar, then a large amount of steel slag produced by the steel plant could be efficiently used to reduce pollution on the environment. 2) The process flow is simple, practical and easy to realize. Equipment used in the process flow is conventional equipment in concrete and block production until now.     3) Grating plate surface is painted with slag pot paint to prevent bonding from steel slag and grating plate. Casting residual slag is cut into small lumps by slag pot grating plate, thus could efficiently avoid the formation of “large slag lump” to avoid harmfulness caused by dropping hammer, gas cutting, etc. 4) Video monitoring is used for production operation. Reduces managers and post holders, consumption and cost.
