Before using the well type multi-purpose furnace, the die-casting crucible must be cleaned to remove the oil, rust, slag oxide on the surface. In order to prevent iron dissolving in the alloy, the crucible should be preheated to 150-200 ℃, spray a layer of coating on the working surface, then heated to 2000-300 ℃, completely remove the water in the coating.

Before using the well furnace smelting tools, the dirt on the surface shall be removed. The parts contacting with the metal must be preheated painted. The tool shall be stained with water, the molten liquid will splash explode.

Clean preheat the alloy before smelting, remove the water adsorbed on the surface. In order to control the composition of the alloy, it is recommended to use the new material 23 in combination with the return material 13.

Melting temperature shall exceed 450 ℃.

The multi-purpose furnace manufacturer needs to clean up the scum on the liquid surface of the zinc pot, supplement the zinc material in time, keep the normal height of the molten liquid level, because too much scum too low liquid level are easy to cause the scum to enter the gooseneck cylinder, pull the steel, hammer head the cylinder itself, causing the hammer head, gooseneck hammer head to be scrapped.

The dross on the molten liquid is stirred calmly with the raking rake to make it gather for taking out.

Charging power transmission:

1、 Charging: before charging, the steelmaker of electric furnace shall check the weight, alloy elements composition of the charging according to the operation plan the batching list, put 1-2% lime of the charging weight into the furnace bottom. After the charge is put into the furnace, the over high charge shall be flattened lifted out, so as to affect the closure of the furnace cover, at the same time to prevent water leakage due to arc striking of the furnace cover.

The top of the basket shall be charged under the command of a specially assigned person. After the furnace cover is opened, the basket shall be quickly hoisted into the central position of the furnace, shall be too high, over biased too low. Keep the chain plate of the basket as low as possible without being stuck. For the secondary feeding, it is allowed to wait for the primary material to be completely cleaned before feeding, so as to avoid the spraying splashing of liquid steel, at the same time, to prevent explosion.

2、 Power transmission: after the charging of the shaft furnace, the furnace cover, electrode, mechanical transmission system, water-cooling system, electrical equipment, etc. shall be inspected before power transmission. If any fault is found, it shall be handled in time to avoid shutdown in the smelting process. Check whether the charging is in contact with the shaft furnace door water-cooling system. If there is any contact, it shall be removed immediately to avoid breakdown after power transmission. If the electrode is long enough, it shall be replaced before power transmission. If the joint position is loose to facilitate the success of one-time well penetration, it shall be tightened first to reduce the shutdown phenomenon in smelting process.

The above is a multi-purpose furnace production line manufacturers to introduce the relevant content, I hope to help you.
