Abstract

The invention relates to a heat treatment device of round steel, in particular a sloping bottom step comprehensive heating furnace, which comprises a preheating zone, a heating zone and a soaking zone, and is characterized in that the preheating zone adopts a sloping bottom type heating furnace structure, the heating zone and the soaking zone adopt a step heating furnace structure, the lower end of the sloping bottom type heating furnace are integrally docked with the front end of the step heating furnace, a blank alignment device and a material stop substep device are arranged on a combination place of hearths of the sloping bottom type heating furnace and the step heating furnace, the material stop substep device comprises two 7-shaped material stop connecting plates which are arranged at an interval in parallel, a left ejection oil cylinder and a right ejection oil cylinder are respectively close to the heads of the two material stop connecting plates, and arc-shaped material supporting plates are arranged on the heads of pistons of the ejection oil cylinders. According to the invention, the advantages of the sloping bottom type heating furnace and the step type heating furnace are combined, the performance of the heating furnace is improved, the working environment of a production workshop is improved, and consumption of labor, gas, water and electricity is reduced as much as possible.

Description

technical field [0001] The invention relates to round steel heat treatment equipment in iron and steel enterprises, in particular to an inclined-bottom walking type comprehensive heating furnace. Background technique [0002] Traditional round steel heating equipment mainly includes inclined bottom heating furnace, walking heating furnace and ring heating furnace. Inclined bottom heating furnace is an earlier heating equipment. The bottom of the equipment is inclined at a certain angle. The operator lifts the billet to the collection area at the end of the furnace. The billet rolls down along the bottom of the furnace by itself and is preheated in turn Heating zone, heating zone, soaking zone; heat supply equipment is arranged on the top of the heating zone and soaking zone, and a number of charging furnace doors and a discharging furnace door are set on the side wall of the heating zone and soaking zone, and manual distribution is required , Dial and discharge. [0003] T...
