1. A water tank is added under the furnace tube, and the material is stainless steel. The water tank is designed with a trapezoidal structure, which is convenient for wire-discharging operation.

2. In the water tank, there is a wire reel just below the furnace tube, which is driven by a motor. The wire reel is made of stainless steel, with a diameter of 40mm and a smooth surface.

3. The lower end of the furnace tube is equipped with a bell mouth, the section is square, and a piece of plexiglass of 100x100mm (the visible area is 70x70mm) is inlaid on the two sides (the front and the right side) to facilitate the observation of the wire.

4. The height of the injection needle into the furnace can be adjusted, the material is stainless steel tube, the outer diameter is 3mm, and it can be connected with the thick tube.

5. The solution injection pump is at the same height as the furnace body, shortening the distance from the syringe to the injection port of the furnace body, and the injection pump and the injection port are connected with a hose.

6. All gas pipelines are changed to stainless steel pipes.

7. The temperature of the nozzle of the liquid injection port in the furnace can be measured, and the flange has been converted into an armored flange, which is convenient for temperature measurement.

8. The lower flange of the furnace tube adopts a water-cooled flange, and the water-cooled machine is provided by the customer.

9. It is necessary to consider whether the heating furnace can be separated from the square tube below, which is convenient for forklift operation and easy to replace the furnace tube.

10. The length of the electric control cabinet is lengthened by 200mm, which is convenient for the installation of the electric control part.

11. The wire-receiving part is controlled by three stepping motors, and the speed is 0-100r/min, which is continuously adjustable.

12. The thermocouple on the flange of the liquid injection port can adjust the distance of penetration, which is convenient for temperature measurement.
