The carbon chromite iron used in the smelting of stainless steel is mainly produced by submerged arc furnaces. This process mainly uses block chromite ore as raw material, and the powder ore needs to be processed into blocks by pressing briquettes before use. The world's chromite ore resources are mainly in powder chromite ore (75% to 80%). At present, the utilization of powdered chromite ore mainly relies on methods such as sintering and pelletizing/briquetting, to block the powder ore and use it for submerged arc furnaces or vertical furnaces. At home and abroad, the treatment of fine ore generally adopts pelletizing and briquetting, using a simple pelletizing/briquetting process, which means that the fine ore is not finely ground and is directly pelletized/briquetted using a dedicated pelletizing machine or a briquetting machine/briquette machine. The pelletizing/briquetting process has low investment and cost.

After sieving the powdered chromite ore, a qualified particle size of chromite ore is mixed with a binder, and then an appropriate amount of water is added and stirred in the mixer. The mixed material is sent to the briquette machine to press the briquettes. After drying, the finished briquette can be put into the furnace for smelting. The basic process flow is: storage--- screening--- crushing--- mixing--- briquetting--- drying.

The selection of binders for powder chromium ore briquettes forming should choose binders with low content of harmful elements such as S and P and good bonding performance. After multiple experiments, our company suggests choosing bentonite and cement with low prices and non polluting chemical composition as binders for smelting alloys.

Due to the large proportion and particle size of powdered chromium ore, it poses certain difficulties for raw material mixing and briquetting. Our company has developed a specialized briquette machine equipment for chromium ore, which has a structure, performance, and material specifically used for powder chromium ore briquette pressing. On the basi s of the configuration of ordinary briquette press machine, the reducer model is increased, and a smaller width pressure roller is used. In this way, the total pressure of the device on the roller surface will increase, and the strength of the finished chromium ore briquette will be greatly improved. In addition, considering the specific gravity of chromium ore powder, the rollers must be wear-resistant and durable,its material selected is 9Cr2 forged steel, with a hardness of over 60HRC, which is very suitable for heavy mineral raw materials. After the formation of powdered chromium ore briquettes, the ore briquettes must meet the following requirements: drop strength (2.0m)>2 times per briquette; Compressive strength>5kg/briquette; Mineral briquette size: customized according to user requirements, generally ranging from 20-100mm; The requirement for impurity elements in ore briquettes is S ≤ 0.06% and P ≤ 0.05%.

Our company's chromium ore briquette pressing machine is currently used in countries such as Iran, Australia, India, etc. After multiple experiments and improvements, we have mastered mature chromium ore briquette pressing technology.
