Problems solved by technology

[0002] During forging, the forging billet should be preheated. At present, most of the widely used gas forging furnaces use cylindrical furnace bodies, which are installed in the slag cleaning box. The preheating oxidation is serious and the heating speed is slow, which not only reduces the quality of the forging, but also reduces the production efficiency, increases the production cost, and consumes a lot of energy

Embodiment Construction

[0022] The coal gasification forging continuous heating furnace is composed of a gas generator 23 and a forging billet heating furnace 24 .

[0023] The gas generator comprises a body of furnace 25, on which a coal hopper 1 and a furnace cleaning hole 22 are installed on the upper cover of the body of furnace 25. A coal discharge valve 2 is provided at the discharge port of the coal hopper 1, and a water jacket 4 is arranged on the inner wall of the furnace part of the furnace body 25. The water jacket 4 is connected with the gas storage tank 9 through a pipeline 26, and the gas storage tank Safety relief valve 8 is installed on the 9. The air storage tank 9 is connected with the primary air inlet pipe 27 through a pipeline. When the water vapor pressure in the air storage tank 9 is greater than the set value, the safety pressure relief valve starts pressure relief. A wind cap 6 is arranged at the lower part of the furnace body 25, and the wind cap 6 is connected with the fi...

Abstract

The invention relates to a gasification forging continuous reheating furnace, comprising a coal gas producer and a forge piece blank heating furnace; wherein the two are connected by a laryngeal chamber. The bottom of the forge piece blank heating furnace is in stepped structure, and a high temperature region and a low temperature region are formed in the hearth. Three burners are arranged in thehigh temperature region in the hearth, the gas inlet of the three burners is fixedly connected with the three gas outlets of the laryngeal chamber, and the gas inlet of the laryngeal chamber is connected with the gas outlets of the gas producer. The flue of the forge piece blank reheating furnace is internally provided with a spiral preheating device, and waste heat of the reheating furnace is utilized to heat the air which enters into the gas producer, thus achieving the aim of energy conservation. The invention adopts optimal short water jacket to directly supply hot gas for gas conversion,fuel and steam consumption is reduced, environmental pollution can be reduced, and forging quality can be greatly improved.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a heating furnace for preheating a forging blank. Background technique [0002] During forging, the forging billet should be preheated. At present, most of the widely used gas forging furnaces use cylindrical furnace bodies, which are installed in the slag cleaning box. The preheating oxidation is serious and the heating speed is slow, which not only reduces the quality of the forging, but also reduces the production efficiency, increases the production cost, and consumes a lot of energy. Contents of the invention [0003] The purpose of the present invention is to provide a large-diameter, low-pressure and short-distance gas exhaust type forging heating furnace body. The kang of the forging heating furnace body is stepped, which can greatly improve the quality of forging preheating and production efficiency, and reduce energy consumption. , and the operation is safe. [0004] The technic...
