Description
Technical Field
The utility model relates to the technical field of tundish metallurgical equipment and heat energy, in particular to a non-contact remote ignition tundish dry-type material mould.
Background
The tundish dry material is a refractory material for a tundish working layer, and is characterized by bulk material, convenient construction, and solidification after heating to form certain strength, so that after construction, a mould is required to be heated to 200-300 ℃ for pre-baking for 90-200 minutes, and the tundish can be demoulded after molding, solidification and cooling, and the tundish is generally effectively baked by using coal gas and compressed air. Firstly, removing water in the refractory layer to solidify the dry material to reach the required strength; secondly, the temperature of the refractory layer on the inner wall of the tundish is increased, and the temperature drop and heat loss of molten steel in the tundish are reduced; thirdly, prevent the bubble under the skin of casting blank, improve casting blank quality. Therefore, the baking effect of the tundish directly influences the quality of casting blanks, the production smoothness and even the safety production.
In the continuous casting tundish baking process in the metallurgical industry, the baking time directly influences the consumption of gas for baking, so that the baking cost is influenced, and the production rhythm is also influenced by the baking time. At present, three ignition modes of the burner nozzle of the mould are respectively manual ignition type off-line baking; baking on line; the three baking modes have advantages and disadvantages respectively. The manual ignition type off-line baking technology is relatively mature, the product price is low, the practicability is strong, the maintenance cost is low, the baking time is long, and the service life of the mould is long. The defect is that a large amount of gas is easy to gather in the mould during ignition, so that a burning explosion phenomenon can be generated, and potential safety hazards are generated for operators. The on-line baking reduces the explosion phenomenon caused by the aggregation of the coal gas in the closed space, is not used for recalling the cladding, has the shortest baking time but also has short service life of the mould, further increases the production cost, has lower utilization rate of the coal gas and causes resource waste. The automatic ignition type off-line baking adopts an automatic control device to replace manual operation, avoids the danger caused by misoperation, and greatly improves the safety of workers. And various electrical elements for improving the safety performance of site construction operation, such as a gas leakage alarm, a low pressure cutting device, a flame detection device, a flame abnormality cutting device and the like, can be arranged on the automatic control module.
