High-temperature box type resistance furnace

Abstract

A high-temperature box type resistance furnace is composed of a furnace frame, a furnace door, a furnace body and heating elements. The furnace body is composed of a furnace shell, a liner and refractory bricks. The furnace body is fixed to the furnace frame, the furnace door is arranged on the vertical face of the front side of the furnace body, and the liner and the heating elements are arranged on the furnace door. The heating elements are arranged on the inner side wall of the furnace body and at the bottom of the furnace body, and the furnace door is closed to form a hearth. The high-temperature box type resistance furnace is characterized in that a furnace door moving air cylinder is fixedly mounted on the vertical face of the front side of the furnace body; a telescopic rod on the furnace door moving air cylinder is connected with the side face of the furnace door; a guide groove is formed in the furnace body; guide wheels are arranged on the upper side and the lower side of the furnace door; the guide wheels on the furnace door are located in the guide groove; and the furnace door moving air cylinder stretches out and draws back to drive the furnace door to slide in the guide groove to achieve opening and closing work of the furnace door, and a limiting piece at the front end of the guide groove is used for limiting. The high-temperature box type resistance furnace has the beneficial effects of being attractive in equipment appearance and high in production efficiency, saving energy and the like.

Description

technical field [0001] The invention relates to the technical field of resistance furnaces, in particular to an all-fiber box-type resistance furnace. Background technique [0002] High-temperature box-type resistance furnace series equipment is mainly suitable for pre-sintering and sintering processes of electronic components, ceramic products, rare earth components, and magnetic materials. At present, the traditional high-temperature box-type resistance furnace is assembled from heavy materials in the furnace structure. The disadvantage is that the thermal tolerance of heavy materials is poor, and the heat preservation effect is not good at high temperatures. The finished high-temperature box-type resistance furnace has large dimensions and heavy equipment, and the entire furnace is prone to slag during sintering. In addition, the traditional high-temperature box-type resistance furnace will crack and collapse, resulting in uneven temperature in the furnace. Even the equi...

At present, the traditional high-temperature box-type resistance furnace is assembled from heavy materials in the furnace structure. The disadvantage is that the thermal tolerance of heavy materials is poor, and the heat preservation effect is not good at high temperatures. The finished high-temperature box-type resistance furnace has large dimensions and heavy equipment, and the entire furnace is prone to slag during sintering. In addition, the traditional high-temperature box-type resistance furnace will crack and collapse, resulting in uneven temperature in the furnace. Even the equipment cannot be used normally, seriously affecting the quality of sintering materials and the use of users
