Abstract

The invention relates to a heating furnace and a heating process thereof, in particular to the heating furnace adopting a regenerative burner and a conventional burner to perform combined heating, and the heating process thereof. The heating furnace structurally comprises a furnace body, and a feeding end wall and a discharging end wall which are arranged at the two ends of the furnace body respectively, wherein the furnace body between the feeding end wall and the discharging end wall is sequentially divided into a heat recovery section, a first heating section, a second heating section and a soaking section; partition walls are arranged between every two adjacent sections; and the furnace body is provided with the regenerative burner used for heating the furnace body, a flat flame burner and a flame adjustment burner. The heating process comprises the following steps of: starting igniting the heating furnace from the flame adjustment burner of the soaking section, and igniting the flat flame burner to switch the second heating section and the first heating section into a thermal storage state of the regenerative burner to finish the ignition heating work. The heating furnace of the invention effectively realizes energy saving, emission reduction and improvement in blank heating quality, greatly reduces spare part production and maintenance cost, and reduces the production cost.

Description

technical field [0001] The invention belongs to the technical field of furnace and cellar engineering, and relates to a heating furnace and a heating furnace heating method, in particular to a heating furnace and a heating furnace heating method using a combination of a regenerative burner and a conventional burner for joint heating . Background technique [0002] The existing regenerative heating furnace generally integrates the regenerative tank and the burner, and through the periodic combustion and smoke exhaust of the paired burners installed on the walls on both sides of the heating furnace, the residual heat in the air can be fully absorbed. Preheat the combustion-supporting air to a high temperature, ignite and burn, that is, use the technology of regenerative combustion to supply heat to the heating furnace. [0003] Especially in the field of iron and steel metallurgy hot rolling, the regenerative combustion method is widely used in billet heating furnaces. Due to...
