1700C Pit-type Furnace

Description

The pit-type resistance furnace (crucible furnace) is composed of an outer shell, a furnace chamber, heating elements, and a temperature control system. It is a periodic operation furnace. Its structural furnace body is a cylindrical deep well. The workpiece is placed vertically from the furnace top or vertically loaded into the furnace for heating using a special hanging tool. It can also be loaded with crucibles such as silicon carbide and graphite as linings.

Features

The large-diameter tube furnace is composed of a heating system, a temperature control system, a working tube, a sealing kit and an automatic opening structure of the furnace cover. It can work under vacuum or atmosphere protection to meet various CVD process requirements. Multiple temperature zones can be set. Realize high uniformity temperature field conditions, and can also be applied to temperature field gradient experiments of materials. This product is widely used in pilot sintering and products in graphene materials, lithium battery positive and negative electrode materials, semiconductor materials, new energy and new material industries batch heat treatment.

Furnace shell

The shell is made of metal Q235 low-carbon steel, and the surface is electrostatically resistant and resistant to corrosion.
The solid double-layer metal frame is combined with the heat-insulating fan structure, and the furnace surface temperature is low
Horizontal use mode, upper opening structure, easy to operate

Refractory material

Multi-layer insulation design, composed of lightweight alumina ceramic fiber and high-quality insulation board backing, does not contain asbestos components, low heat loss and low energy consumption

Heating system

High-quality heating elements are distributed around the furnace, and heat is freely radiated in the furnace cavity, which is energy-saving and efficient, and has a long service life.
The heating elements are evenly arranged around the furnace, thus achieving good uniformity in the furnace.

Temperature Control Panel

PID with SSR/SCR control mode, precise temperature control
International standard thermocouple, long service life
Equipped with heating indicator light and over-temperature alarm buzzer

Program Controller

Advanced controllers that meet complex process requirements
Simple and direct operation, flexible programming
Programmable 32 program segments
Over temperature and fault alarm, automatic safety protection
