Low Ash Metallurgical Coke

Low ash metallurgical coke advantages

The advantage of low ash metallurgical coke is very significant.

High fixed carbon content

It can continuously and stably release high heat at high temperature, provide sufficient energy for metallurgical smelting. And ensure the efficient smelting process.

Low ash content

Effectively reduce the introduction of impurities, reduce the amount of slag generation. It helps to improve the purity and recovery of metal.

Low sulfur content

In the smelting process of metal pollution is small, can effectively improve product quality.

Висока механічна міцність

It is not easy to break during transportation, loading and unloading and reaction in the furnace, ensuring the permeability and reactivity of coke. Make the metallurgical reaction more adequate and stable.

Developed pore structure

The contact area with oxygen and ore is increased. The REDOX reaction rate is accelerated and the smelting efficiency is improved.

Types of low ash metallurgical coke

Steel coke

You can mainly use it in the blast furnace ironmaking process, requiring coke to have high reactivity and thermal shock resistance. It can quickly reduce iron ore to hot metal, and ensure the forward flow of the blast furnace. The control of sulfur, phosphorus and other impurities is more strict to ensure the quality of steel in the steelmaking process.

Foundry coke

In cupola used in the casting industry, the coke needs to have good lumpiness, strength and low porosity. This ensures that the heat can be provided stably during the iron smelting process, maintain the temperature and composition of the hot metal. And the foundry coke makes the castings with higher quality, better surface finish and fewer internal defects.

Uses of low ash metallurgical coke

Steel industry

In blast furnace iron-making, low ash metallurgical coke, as the main fuel and reducing agent, reduces iron oxide in iron ore to liquid hot metal. While it provides the heat required to maintain the high temperature environment in the доменна піч. Ensure the continuous and stable operation of the blast furnace. Its quality directly affects the output and quality of pig iron and the life and production cost of blast furnace.

Non-ferrous metal smelting

In the smelting process of copper, lead, zinc and other non-ferrous metals, low-ash металургійний кокс also plays an important role. For example, in the reflection furnace or blast furnace of copper smelting, you can burn coke as a fuel to produce high temperature. So that the copper element in the copper ore can be melted and separated. In lead and zinc smelting, coke participates in the REDOX reaction to promote the reduction smelting and refining process of lead and zinc concentrate. Improve the recovery and purity of non-ferrous metals, reduce energy consumption and production costs in the smelting process. And improve the economic benefits of enterprises.

Machinery manufacturing

In the casting process, you can use low ash metallurgical coke in cupola to provide a stable heat source for melting metal. It ensures that the liquid metal has good fluidity and filling ability. High-quality low ash metallurgical coke can ensure the smooth progress of the casting process, reduce the defects of castings, improve the overall quality and performance of mechanical products. And enhance the market competitiveness of machinery manufacturing enterprises.
