Problems solved by technology

However, the existing furnace door is made of refractory bricks, which is troublesome to construct, and the heat preservation performance of the furnace door is poor.
Moreover, it is extremely inconvenient or impossible to overhaul. If it is necessary to overhaul, it needs to be completely dismantled and then bricked, resulting in a waste of materials and manpower.

Embodiment 1

[0026] like figure 1 As shown, the industrial kiln door of the present invention has a handle 2 welded on the cross frame 1, the body 3 is wrapped outside the frame 1, and the body 3 is made of heat-resistant and heat-insulating material poured on the frame 1.

Embodiment 2

[0028] The manufacturing method of the industrial kiln furnace door described in Example 1: first, the temperature-resistant and heat-insulating pouring material containing 4kg polycrystalline mullite fiber, 3kg zirconium-containing fiber and 2.5kg high-alumina fiber is mixed with 0.5kg of binder , crushed to 180 mesh with a mixer; put the pre-made skeleton into the mold, pour the mixed material on the skeleton in the mold to get the blank, squeeze the blank with a hydraulic press, and squeeze out the moisture in the blank; put the formed The blanks are dried in the sun for 4 days; the dried blanks are baked in an oven at 300°C for 24 hours; the baked blanks are calcined in an electric kiln at 1200°C for 48 hours; the calcined blanks are according to the actual industrial kiln door In some cases, use an electric saw to process the shape and size of the furnace door to a suitable size, and finally smooth it with sandpaper to obtain the desired furnace door.

Abstract

The invention discloses a furnace door of an industrial furnace, which comprises a framework, a handle and a body, wherein, the handle is welded on the framework; and the body is casted on the framework by a temperature-resistant and insulating material. The invention also discloses a method for manufacturing the furnace door of the industrial furnace and a formulation of the temperature-resistant and insulating material used for the furnace door of the industrial furnace. The furnace door of the industrial furnace is an integrated furnace door which is manufactured according to the size of the furnace mouth, matched with the furnace mouth, can be arranged on the furnace mouth without other materials for arrangement, and has the advantages of simpleness and convenience, convenient detachment and maintenance without destroying the furnace mouth, thereby greatly reducing cost, and saving time and manpower. The furnace door of the industrial furnace is low in cost.

Description

technical field [0001] The invention relates to an industrial kiln door, its manufacturing method and the casting material used. Background technique [0002] Industrial furnaces are widely used in ceramics, magnetic materials, electronic materials, metallurgy and other industries. Furnace doors are an important part of industrial furnaces. The existing furnace doors are made of refractory bricks. Refractory bricks can prevent the heat in the furnace from dissipating to the outside of the furnace, reducing the heat consumption in the furnace. However, the existing furnace door is made of refractory bricks, which is cumbersome to construct, and the heat preservation performance of the furnace door is poor. The heat in the furnace is still radiated to the outside of the furnace body through the refractory bricks, thereby causing the kiln to dissipate heat. And, overhaul is extremely inconvenient or can't overhaul, if want overhaul, need all to dismantle, build with bricks aga...
