Audited Supplier | 1. Main Ingredient: Main ingredient: Calcium oxide Chemical formula: CaO |
| 2. Physical and chemical properties: white small pieces or powder, uniform particle size, no peculiar smell, high activity (350ml as calcium oxide of 90), short dissolution time. |
| 3. Product advantages: At present, lime produced from kiln shapes such as Maierz kiln, rotary kiln, and double-chamber shaft kiln can become active lime. The main symptoms are high calcium content, large lime pores, small specific gravity, and high activity 3. Fast response. In the smelting and chemical industries, the general reaction time is limited. If the calcium content of lime is high and the activity is not high (uneven heating of the lime calcination process causes the calcium oxide crystals to grow too fast and the pores between the crystals are small), then the limited If the reaction is not completed within the time, the unreacted lime will be discharged as waste residue, which will increase the amount of lime and increase the production cost of the customer, and activated lime can solve this problem. |
| Smelting industry: Oxygen converter steelmaking smelting time is shortened, industrial development began to use activated lime in the 60-70s. After entering the 1990s, with the development of smelting technology, especially oxygen top-bottom combined blowing and refining outside the furnace, the range of metallurgical steel types has been continuously expanded; the development of ultra-high power electric furnace steelmaking; and the requirement to achieve automatic control of the steelmaking process, this Lime is required to have good activity, stable composition, low impurity content (especially S and P content), and appropriate particle size, and activated lime meets its requirements exactly. |
| The use of activated lime in steelmaking brings more benefits than the use of ordinary lime: |
| (1) Shorten the oxygen blowing time by about 10%; (2) Increase the yield of molten steel by ~ 1%; (3) Save 20% -30% of lime consumption; (4) Increase the amount of scrap steel by about 2.5%; (5) Fluorite Consumption saving 25% -30%; (6) Greatly increase the life of converter lining; (7) Improve the desulfurization and dephosphorization fruit; (8) Increase the steel-making temperature hit rate from 60% to 75%; (9 ) Helps to accelerate the automatic control of the steelmaking process. |
| 4. Scope of application: smelting industry, paper making, chemical industry, environmental protection and other industries |
| 5. Application: It is mainly used for smelting of ferroalloys such as seed steel, stainless steel, ferromanganese (medium manganese), soldering iron, etc., and S, P, Si slag-making agent for casting. |
