Distributing Method of Walking Beam Slab Heating Furnace

Abstract

The invention discloses a material distribution method of a walking-beam-type plate billet heating furnace. The walking-beam-type plate billet heating furnace comprises a plurality of side burning nozzles arranged at the lower part of a furnace body. The material distribution method comprises the following steps: only putting plate billets to be rolled on the side, near a rolling mill, of the walking-beam-type plate billet heating furnace; and keeping an equal distance between the end part, near the side of the rolling mill, of each plate billet and a furnace wall, near the side of the rolling mill, of the walking-beam-type plate billet heating furnace, wherein the distance between the end part, near the side of the rolling mill, of each plate billet and the furnace wall, near the side of the rolling mill, of the walking-beam-type plate billet heating furnace, is shorter than the distance between the end part, the side of the rolling mill, of each plate billet and the furnace wall, near to the side without the rolling mill, of the walking-beam-type plate billet heating furnace. According to the material distribution method, the plate billets without fixed sizes are effectively heated in the walking-beam-type plate billet heating furnace; each plate billet and the end part, which needs to be rolled, of each plate billet, are consistent in temperature after the heating of the plate billets, so that the stability of the plate billets during a rolling process is improved.

Description

Technical field [0001] The invention belongs to the field of metal pressure processing. Specifically, the invention relates to a method for distributing a walking beam type slab heating furnace. Background technique [0002] Steel rolling heating furnaces are mainly divided into push-steel heating furnaces and walking-type heating furnaces. Compared with push-steel heating furnaces, walking-steel heating furnaces have the following advantages: flexible material transportation, and all charge can be discharged out of the furnace when necessary; The slabs are placed at intervals in the furnace, which can be heated evenly and quickly; the arch steel and sticking failures of the push-steel heating furnace are completely eliminated. [0003] Walking beam heating furnaces are divided into walking beam heating furnaces and walking bottom heating furnaces. Compared with walking bottom heating furnaces, walking beam heating furnaces can simultaneously heat the upper and lower surfaces of th...

Problems solved by technology

For a walking beam slab heating furnace with a width between two furnace walls not less than 8m, the length of the flame ejected from the side burner limits the size of the titanium billet and the heating of the titanium billet in the walking beam slab. Furnace distribution method

Specifically, if the length of the titanium billet with centering cloth in the walking beam slab heating furnace is so short that the length of the flame sprayed from the side burner cannot effectively heat the lower surface and end of the titanium billet, then The side burners of the walking beam slab heating furnace cannot effectively heat the shorter titanium billet; if the titanium billet is balanced in the walking beam slab heating furnace, due to the The distance between the two furnace walls of the furnace is not less than 8m, which makes the temperature uniformity in the furnace width direction of the walking beam slab heating furnace poor, resulting in differences in the temperature of the titanium billet with balanced distribution along the furnace width direction, Thus affecting the stability of the titanium billet during the rolling process
