When this situation occurs, it means that a good lining material has been used, pay attention to the role of the lining material, and find records to obtain better lining materials. Acid furnace lining manufacturers introduce remedies which? To solve the problem, it is worth remembering the following four points:

       1. Keep it steady

       2. Every procedure or step needs to be recorded

       3, often go into the workshop, understand the electric furnace. Close usage to get first - hand data

       4, systematic analysis, generally change one parameter at a time

The above information is provided by the furnace lining material manufacturer

       The solution to the problem

       1, if you find a problem, repeat all steps once, but pay attention to the details, do it yourself, as much as possible. Good melting method.

       2. The furnace building and oven sintering process must be supervised, including the placement of the crucible die, the feeding method, the furnace building method (especially the bottom corner part), and the measurement of the knotting density. It is also necessary to pay attention to the changes in the furnace building tools, furnace building personnel and furnace building procedures.

       3, from room temperature to 1100℃ whether continuous temperature measurement, heating rate and the original difference, need to make a record.

       4, (when melting) whether the liquid level reaches the predetermined height, whether the sintering temperature meets the requirements, and whether the maintenance time of the heat preservation process is enough, often check the thermocouple and thermometer table.

       5, after the oven sintering, a few days before use, the metal liquid level should be high, good full furnace operation, do not stop the furnace a week or half a month before, so that the lining is completely sintered, but if there is only one operation, you must empty the metal liquid, add the frit, electric heating to more than 800℃ and heat insulation until the lining sintering is enough to withstand the defects caused by sudden cooling. Conditionally, it can be kept at 800℃ by burning gas after the metal liquid is produced.

       6, start the first few furnace melting, should use clean low-carbon charge, if conditions, can set up a special storage warehouse.

       7, into the normal melting mode, it is necessary to record the type, amount and method of melting materials, cleanliness, observation and analysis of mixing, and compared with the original.

       8, find the reason for metal analysis or adjustment delay, the reason for the delay of the ladle to the electric furnace, etc., overheating is the enemy of the furnace lining, affecting its life. The rate of molten metal flow can be compared with the rate of molten metal (kg/h) in previous successful examples.

       9, ask about the past (including the present situation) slag production and removal of slag methods, to see if there are abnormal changes or different reactions.

       10, for the electric furnace and control equipment, refractory layer and power equipment, etc., have not been investigated or replaced recently (thermal conductivity, reinforced brick or cooling water temperature changes can have a significant impact on the hot surface temperature and erosion resistance)

       11. Any changes in workers and managers, and the relationship between them, should pay special attention to and supervise the operation of new workers.

       12, whether the production of the melting workshop is normal, if the workers are on the alert for a long time to cope with the changing needs of the work workshop, in this case, the life of the furnace lining is difficult to improve.

       13, record each observation, because many times, it accounts for three or four possible solutions to the problem, these records can help you think logically, and remind you to observe and pay attention to the problem in the future.

       14, if the analysis of the possible causes of the problem, then make changes as much as possible, only change one parameter at a time, because make too many changes, will not get the result, can not find the real cause.

       15, your operation of the electric furnace. For the sake of familiarity, ask questions truthfully. This is more than any outside invitation... More problem solving.
