Coke Oven Furnace Top Charging, Bell type furnace top charging equipment

Product Description:

The function of the top of the blast furnace is to reasonably distribute the charge in the proper position in the blast furnace according to the conditions of the blast furnace. There are two types of furnace top charging equipment: bell top charging equipment and bell-free top charging equipment. The bell-type furnace top charging equipment mainly includes large and small bells, large and small hoppers, and large and small bell hoists and distributors.
The advantages of the bell-type furnace top charging equipment are its simple structure, easy manufacture and low cost. The disadv

antages are the heavy equipment, poor distribution effect, low roof pressure, and poor gas utilization. Newly built blast furnaces have almost no longer adopted bell roofs, and blast furnaces above 300m3 are gradually transformed into bellless roofs during major repairs.

The bell-free furnace top charging equipment mainly includes loading tank, discharge tank, upper sealing valve, lower sealing valve, material flow regulating valve, airtight box, distribution chute, pressure equalizing equipment, etc.

The bell-free furnace top charging equipment has good high-pressure sealing performance and flexible distributing means, which can make the blast furnace make full use of gas energy and keep the blast furnace running smoothly; at the same time, it operates reliably, with few vulnerable parts, and convenient and quick maintenance.
