Working procedure of Semi-coke production

 

The powders of semi coke are graphitized to provide test carbon content upsides of more than 95%. Semi coke, a result of the compound business, is another fuel for impact furnace infusion in China. Strong squanders got from metallurgical ventures represent a huge danger to the climate. The use and removal of these strong squander are significant worries on the planet. Semi-coke created in coal-based direct decrease cycle of iron metal is a side-effect and its reasonable usage isn't accessible up until now. To deal with it appropriately, the attributes of this result were extensively examined. Progress of examination techniques was utilized to show its mineral arrangements, petrography, and physical-synthetic properties. The outcomes uncover that the semi-coke has bad wash ability. The fixed carbon substance of semi-coke arrives at 76.11% and the gross calorific worth is 28.10 MJ/kg, the two of which are like those of conventional sinter coke breeze.

Applications

Basic coke items are for the most part utilized in metallurgical businesses, for example, impact heater ironmaking and projecting. Semi-coke can't be utilized in impact heater creation. Notwithstanding, in ferroalloy, calcium carbide, manure, and different businesses, Semi-coke can totally supplant general coke, and its quality is superior to numerous public norms for metallurgical coke, foundry coke, and ferroalloy uncommon coke. Consequently, Semi-coke is improving the nature of downstream items. Saving energy has higher application esteem as far as lessening creation costs and expanding yield. Simultaneously, Semi-coke likewise has improved power in the terms of impact heater infusion, creation of carbonized materials, and actuated carbon.

Creation Technology

The creation of Semi coke is for the most part dependent on low-temperature dry refining, and the dry refining temperature is by and large around 600 ℃.

Costs of semi-coke

Because of contrasts in crude materials and cycles, the market cost of semi-coke is less when compared to the normal coke. Accepting 2006 for instance, the market cost of semi-coke was approximately 300 yuan/ton, and the normal cost of the least grade coke (10-25 mm) was likewise 760 yuan/ton. The moderately less market value makes semi-coke items own large market combat. All in all, contrasted with coke, semi-coke has a more extensive scope of utilization, more grounded practicability, and minimal price. Accordingly, semi coke is currently one of the favored materials for allow smelting.

Semi-coke briquettes

Direct family utilization of natural crude coals for cooking and warming with no air contamination control gadget has caused genuine indoor and open-air climate issues by radiating particulate matter (PM) and vaporous poisons. The investigation analyzes family emanation decrease by changing from anthracite coals and natural bituminous to handled semi-coke briquettes. Two normal ovens were utilized to test outflow qualities when consuming 20 crude coal tests generally utilized in private warming exercises and 15 semi-coke briquette tests which were produced using bituminous coals by mechanical carbonization treatment.

Quality

In contrast to coke items, semi-coke production has the upsides of low dampness, low phosphorus, low sulfur, high fixed carbon, low debris content, high compound movement, high explicit resistivity, and so on "three highs and four lows."
