Efficient energy-saving high-temperature electric furnace with lifting furnace door and full-fiber hearth

Abstract

The invention discloses an efficient energy-saving high-temperature electric furnace with a lifting furnace door and a full-fiber hearth. Compared with a traditional electric furnace, the electric furnace has obvious innovation advantages in aspects such as structural design of a furnace body, selection of hearth materials and temperature control. The furnace door is arranged at the bottom of the electric furnace and controlled to rise and fall by a lead screw, calcined samples can be conveniently placed on the furnace door after the furnace door falls, loading capacity is high, the furnace door is excellent in tightness after the furnace door rises and is closed, and heat is not easily dissipated from a furnace mouth. By the aid of the multilayer graded temperature-resistant full-fiber hearth, heat insulation performance is excellent, heat storage capacity is low, the energy-saving effect of the electric furnace is quite remarkable, the temperature is rapidly raised and reduced, a furnace roof does not easily collapse by the aid of unique assembly structure design of the furnace roof, all sides of a heater are heated, temperature fields in the furnace are uniform, a temperature control system is advanced and simple and convenient to operate, running voltage, current, power, electricity consumption and the like are displayed in a centralized manner by the aid of a PID (proportion integration differentiation) intelligent temperature control instrument and an intelligent power display instrument, the electric furnace has an over-current alarm function, and heating elements are low in load, long in service life and convenient to replace.

Description

technical field [0001] The invention belongs to the technical field of electric furnace manufacturing, in particular to a high-efficiency, energy-saving and high-temperature electric furnace with a door-lifting full-fiber furnace, which is suitable for sintering and heat treatment of materials such as ceramics in enterprises, universities, scientific research institutes and other units. Background technique [0002] High-temperature electric furnaces are widely used in industrial production and new material research. The traditional high-temperature electric furnace is usually a box-type furnace body structure, the furnace door is opened in front, and the heating elements are arranged on both sides. The sintering waste rate is high; it is very inconvenient to take and place samples through the furnace mouth, especially when sampling at high temperature or when the furnace is full of samples, and it is easy to damage the furnace mouth and heating elements. The effective spac...
