Abstract

The invention relates to an improvement of a wear resistant steel ball heat treatment heating furnace, and concretely relates to an annular heating furnace with a rotary furnace bottom. The annular heating furnace is provided with a furnace body, feeding and discharging ports, combustors, a maintenance furnace gate and a smoke outlet; and the bottom of the furnace body is respectively provided with a rotary driving mechanism, a lateral positioning mechanism and a support raceway; a hearth has an annular structure, the bottom of the hearth is a water seal tank provided with a furnace bottom, and the furnace bottom is composed of a heat insulation panel, a skirt rim sealing plate, a structural support, a tooth ring, an annular rail surface and a baffle ring. The problems of large labor intensity of an operator, low work efficiency, large hidden safety trouble, unstable heating quality and high energy consumption per unit output of present wear resistant steel ball quenching treatment heating furnace with inclined-bottom hearths are solved, and present wear resistant steel ball heat treatment heating furnaces are mainly improved in the invention.

Description

technical field [0001] The invention relates to the improvement of a heat treatment heating furnace for wear-resistant steel balls, which is a rotary bottom annular heating furnace. Background technique [0002] When beneficiating gold ore, nickel ore, copper ore, iron ore, small metals and precious metals in the metallurgical industry, the ore is crushed by a ball mill for beneficiation, and the wear-resistant steel balls in the ball mill need to be quenched; the prior art wear-resistant steel The ball quenching treatment is heated by an inclined-bottom furnace heating furnace. The inclined-bottom furnace heating furnace is a longitudinally arranged kiln structure. The furnace bottom in the inclined-bottom furnace heating furnace is arranged obliquely. The furnace door is equipped with a discharge furnace door at the end of the furnace; the wear-resistant steel balls are fed at the head of the furnace body, and the wear-resistant steel balls roll through the preheating zone...
