Charge into the furnace and power supply of the pusher furnace:

1. The charge of the push-slab furnace is put into the furnace: Before the charge is put into the furnace, the electric furnace steelmaker should review the weight, alloy elements and composition in the charge according to the operation plan and batching list, and put 1~2% lime on the bottom of the furnace. . After the charge is put into the furnace, the excessively high charge should be flattened or lifted out, so as not to affect the fastening of the furnace cover, and at the same time to prevent the furnace cover from being arced and leaking.

The charging of the top of the material basket must be directed by a special person. After the furnace cover is opened, the material basket should be quickly hoisted into the center of the furnace, and it should not be too high, too low, or too low. Keep the chain plate of the basket as low as possible without being damaged. For the secondary feeding, do not wait for the primary material to be completely cleared before feeding, so as to avoid molten steel spraying and splashing, and at the same time to prevent explosion

15.Atmosphere box furnace sealing technology

1.1 Infrared instrument and oxygen probe can be used as sensors for multiple control to control the carbon potential of the atmosphere and the depth of the carburized layer.

Technical thinking

1. The airtightness and atmosphere uniformity of the atmosphere box furnace. A high-level, high-quality multi-purpose furnace should have:

(1) Good sealing performance:

(2) The atmosphere is stable and the composition fluctuation is small;

(3) Furnace temperature control, with good furnace temperature uniformity;

(4) The monitoring system reflects timely and accurately.
