Electric heating full fiber trolley furnace

Abstract

The invention discloses an electric heating full fiber trolley furnace. The electric heating full fiber trolley furnace comprises a trolley furnace main body, an upper sliding furnace door, a cast steel furnace bottom plate, a furnace wall heating center and a furnace blower. The outer wall of the trolley furnace main body is tightly attached with a section steel shell, the outer wall of the mainbody of the trolley furnace is closely attached with a full fiber lining, the bottom of the trolley furnace main body is welded with wall feet, the front part of the trolley furnace main body is movably connected with the upper sliding furnace door, and the internal activity of the main body of the trolley is connected to the bottom of the cast steel furnace. The electric heating full fiber trolley furnace is closely attached with an all-fiber lining on the inner wall of the main body of the trolley furnace. Because the fiber is a substance which has low weight, poor thermal conductivity but good heat storage, so when the trolley furnace working, the all-fiber lining can lock the heat generated inside the trolley furnace to prevent the heat from spreading. The use of less electric energy can bring higher heat to the trolley furnace and solve the problem that the heat of the trolley furnace in the past is severely dissipated, resulting in serious waste of electric energy.

Description

technical field [0001] The invention relates to the field of bogie furnaces, in particular to an electric heating full-fiber bogie furnace. Background technique [0002] The bogie furnace is a kind of equipment that uses heating elements to generate heat and heats and quenches steel and other workpieces in an iron furnace with good heat preservation. many. [0003] The Chinese patent with the authorization announcement number CN207095290U discloses a full-fiber trolley furnace, including a furnace body, a box body is installed at the bottom end of the furnace body, and the bottom of the furnace body can be heated by the flue gas. The heat from the residual gas heat continues to heat the furnace body, which can make better use of this part of the heat to save energy and reduce consumption of the furnace body. To prevent the toxic substances in the flue gas from being discharged into the air and cause pollution to the environment, but the heat preservation performance of the...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an electrically heated all-fiber trolley furnace, which solves the problem that the heat of the trolley furnace in the past is seriously dissipated, resulting in a serious waste of electric energy, and solves the problem of the trolley furnace in the past. The heat diffusion speed is slow, the temperature rise rate in the furnace cavity is low, and the heat utilization rate is not high. It solves the problem that the heating tube in the past can only diffuse slowly after heat dissipation, and solves the long-term accumulation of scale to cover the electric heating tube on the bottom plate. The problem that the heat covered by the electric heating tube on the bottom plate cannot be volatilized and damaged is solved, and the problem that the internal heating components are still heating when the furnace door of the trolley furnace is opened causes serious energy loss.
