Box type electric furnace hearth structure and furnace material of frit furnace

The material of the frit furnace is made of ceramic fiber, which has small heat capacity and fast heating (45 minutes can be raised to the set temperature), saving energy, using high quality crucible and durable. The intelligent digital display programmable temperature control table is used for automatic temperature rise, heat preservation, temperature reduction and over temperature protection, and a silicon molybdenum rod is used as a heating element. Temperature control accuracy ± 1oC.

1, microcomputer control, easy to operate, programmable, automatic temperature rise, automatic insulation, automatic cooling.
2, control accuracy: ± 1 ° C furnace temperature uniformity: ± 1 ° C (depending on the size of the heating chamber).
3, energy saving
4, the furnace temperature is close to room temperature
5, the temperature rises quickly (heating rate 20-40 ° C / min).
6, imported refractory materials, good insulation performance, high temperature resistance, resistance to rapid cooling
7, temperature category: 1400 ° C 1600 ° C 1700 ° C 175O ° C four

The box type electric furnace thermocouple converts the furnace temperature into a voltage signal and adds it to the microcomputer temperature control regulator. The regulator compares this signal to the programmed settings and outputs a tunable signal. The adjustable signal is used to control the trigger, and then the trigger triggers the voltage regulator to achieve the purpose of adjusting the voltage of the electric furnace and the temperature of the electric furnace.
Box type electric furnace hearth structure

The box-type electric furnace is carefully designed and adopts the most advanced technology. The furnace body has novel appearance and reasonable structure. The outer casing adopts the national standard steel, and its outer casing is sprayed with the advantages of temperature resistance, durability, oxidation resistance, acid resistance and hydrazine resistance; the carefully matched color is the product beautiful and durable! The furnace materials are all made of imported Morgan fiber. The furnace is assembled by several refractory fiber blocks, which greatly avoids the phenomenon of quenching and hot cracks.
Heating elements (distributed around the furnace).

1. The silicon molybdenum rod electric heating element is a resistance heating element based on molybdenum silicide. The sintered molybdenum silicide article is heated to a high temperature in an oxidizing atmosphere, and a dense quartz glass film is formed on the surface to keep the article from oxidation. Therefore, the molybdenum molybdenum rod element has a unique high temperature oxidation resistance. The maximum use temperature is 1750 ° C under an oxidizing atmosphere. The resistance of the silicon molybdenum rod component does not change with the length of use (the resistance increases with increasing temperature), that is, it does not age, so new and old components can be mixed. The mechanical properties of the silicon molybdenum rod element are similar to those of other ceramic products, and the brittle material is easily broken at normal temperature, but it can be avoided by proper use and proper installation.

common problem

1. The electric furnace is not heated: check the incoming electricity, and the electric furnace internal insurance
2, the meter shows nnn1: the thermocouple is damaged or the room temperature is too low
3, the temperature is not controlled: MAN manual indicator is light (normal does not light)
4, there is voltage and no current: the heating element is damaged
5, the instrument display END, can not start: it means the end of the run, in the operation if the instrument is turned off after the start
