Front-back door opening multi-chamber forging furnace adopting blast furnace gas as fuel

Abstract

The invention discloses a front-back door opening multi-chamber forging furnace adopting blast furnace gas as a fuel. The front-back door opening multi-chamber forging furnace has a furnace body; steel structural supports are arranged around the furnace body; a heating chamber I, a heating chamber II, a heating chamber III and a heating chamber IV are arranged in the furnace body, wherein a furnace wall is arranged between the heating chamber II and the heating chamber III; four loading ports are formed in the same one sides of the four heating chambers; loading furnace doors are arranged on the loading ports; four discharge ports and discharge furnace doors are arranged in opposite positions of the other sides of the four heating chambers; blast furnace gas flat flame burners are respectively arranged at the tops of all the heating chambers; the two blast furnace gas flat flame burners at the tops of the heating chamber I and the heating chamber II are connected through four two-position three-way reversing valves; the two blast furnace gas flat flame burners at the tops of the heating chamber II and the heating chamber III are connected through another four two-position three-way reversing valves; and the operation of two two-position three-way reversing valves is controlled through a controller. The front-back door opening multi-chamber forging furnace is simple in structure and convenient to operate, can adopt the blast furnace gas as the fuel, and is high in heat utilization rate.

Description

technical field [0001] The invention relates to the technical field of industrial furnaces, in particular to a multi-chamber forging furnace with front and rear opening doors using blast furnace gas as fuel. Background technique [0002] In the field of heat treatment technology, industrial forging furnaces are often involved. Existing forging furnaces generally use a single heating chamber or a double-chamber heating furnace with a front door. Multiple single-chamber heating furnaces have a large heat dissipation area and a large amount of heat loss. Each In the heating chamber, the charging port and the discharging port are located at the same position, which is not conducive to the streamlined operation of charging and discharging. Moreover, common burners are generally used for heating, which cannot be used for blast furnace gas with low calorific value. Cause fuel waste, and can increase the impact on environmental pollution.
