heating rate

RT-200℃≤25min.

Temperature fluctuation

≦ 0.5℃ Accuracy 0.1℃

Temperature uniformity

It is commonly used at 200℃ ≦ 2%℃ (collected at three points on the left, center and right under no-load condition)

Outer box temperature

Do not exceed 20℃ of room temperature, except for the door periphery, except for the air inlet/outlet.

Circulating air mode

The right-hand side wind is dumped, heated by the heating pipe, flows horizontally through the product, and then returns air on the left.

Structural characteristics of box body

Box features

1. Intelligent temperature controller is adopted for continuous heating between constant temperature stages, with low power consumption, uniform temperature and multi-channel digital display for temperature detection;                                                                                                   

2. The punching type air plate is adopted to facilitate the operators to clean the interior and reduce the secondary pollution of the products;

3. The heating pipe is connected with 500℃ high temperature glass fiber, which is safe and durable.

sheathing material

It is made of SS41＃1.5T cold plate, bent and welded with baking powder of specified color.

Liner material

It is made of SUS430#1.5 mirror stainless steel plate, which needs reinforcing ribs and is acid and alkali resistant.

surface treatment

1. Surface grinding, polishing and phosphating (which can increase the corrosion resistance of metals and the adhesion of paints);

2, high temperature baking varnish, can prevent rust, corrosion resistance;

3. The color is "wrinkle white".

thermal insulation (material)

120K aluminum silicate glass fiber rock wool is adopted with a thickness of 100mm, which has the characteristics of non-combustibility, strong heat insulation and the like;

Material characteristics: ①50mm thick white glass, temperature resistance of 1770℃, high density, good compactness, strong thermal shock resistance and excellent compressive strength; ② ceramic fiber board, with temperature resistance of 1260℃, hard texture, excellent toughness and strength, excellent wind erosion resistance, non-expansion upon heating, light weight and convenient construction; ③ Aluminum silicate cotton has low heat capacity and low temperature导热率、高耐火度和高热敏性，优良的抗风蚀性能和抗机械冲击性能，优良的吸音及防火性能。

sealing material

The sealing strip is made of T-shaped foamed silicone rubber strip, which can resist temperature and deformation, has excellent sealing effect and does not leak heat.

door

Left and right 180-degree single door structure design, long handle door lock for oven, high-density closing,

air-proof

air interchanger

1. The side of the furnace body is provided with an air inlet and an air outlet;

2, equipped with regulating valve, can adjust the air flow, make the furnace temperature more uniform.

Temperature measuring device

A temperature measuring point-mother head is set outside the box for convenient temperature detection. Three points are reserved for each door (see schematic diagram).

Shelving device

A single box body is divided into 2 layers, equipped with 2 stainless steel grating disks, and fixed guide rails at both sides (the number of shelves and grating disks can be configured according to requirements).

Supports and casters

With sliding casters and adjustable support cups.

control

System

heater

1. Total heating power is 7kW (3.5KW)； for a single box);

2. Adopt the custom-made ceramic disc heating tube, which has no open flame, pressure resistance and good heat dissipation effect;

3, the heating speed is high and the heating is stable;

4. The heating pipe is connected with 500℃ high temperature glass fiber, which is durable.

temperature controller

Shengang RKC-900 temperature controller is used to control the opening and closing of Taiwan Province Xuanrong SSR for temperature control, digital setting, PID self-calculation, LED display and overtemperature alarm.

control system

1, switch button control, overtemperature abnormal sound and light alarm;

2. The electric control cabinet is controlled independently and fixed on the right side of the cabinet, with good heat dissipation effect.

Overtemperature protection thermostat

1, when the temperature exceeds the overtemperature protector set point, alarm and automatically cut off the heating power supply, alarm until the operator to remove;

2, add digital display overtemperature protection device, prevent abnormal temperature control heating out of control.

security apparatus/device/equipment

1, overtemperature stop heating and alarm device;

2. Motor overload protection device;

3, control circuit short circuit and overload protection;

4, leakage protection device (chint leakage circuit breaker);

5. Power supply reverse preventer etc. meet the international safety standard;

6. Enclosed design of electric box, ventilation device (4-inch cooling fan) with dust filter.

other

1. The contactor adopts Taian/Zhengtai series;

2. The relay adopts Omron series;

3. The solid state adopts the Taiwan-made Xuanrong series;

4. All wiring terminal numbers and major electrical components are clearly identified by number tubes.

Chu, all electrical parts have leakage protection device, reliable grounding system;

5. All air pipes, wires, magnetic sensors, optical fibers, photoelectric sensors, etc. are clearly indicated, numbered pipes are marked, adhesive blocks are not allowed to bind tapes during wiring, and reliable fixing method is required (the method of fixing the heat dissipation slot is adopted);
