Abstract
The utility model relates to a high-temperature-resistant and wear-resistant grate beam protection plate for a sintering machine, in particular to a protection plate on a grate beam of an iron-making sintering machine. The high-temperature-resistant and wear-resistant grate beam protection plate for the sintering machine solves the problem that the prior protection plate of a grate beam is short in using time. The protection plate of the grate beam comprises a left vertical plate, a right vertical plate and a horizontal plate. The left vertical plate and the right vertical plate are respectively fixed on the lower edges on two sides of the horizontal plate to ensure that the left vertical plate, the right vertical plate and the horizontal plate form a U-steel shape; two ends of the left vertical plate are respectively provided with a bolt hole; bolt holes penetrate through the right vertical plate; a plurality of notched grooves are evenly distributed on two sides of the horizontal plate; and alloy wear-resisting bodies are filled in the notched grooves in a bead welding mode. In the using process, the top ends of two sides of the protection plate of the grate beam are positions which are fastest worn down, and therefore the ally wear-resisting bodies are placed in the positions, and accordingly heat-resisting and wear-resisting capability is improved, and service life is correspondingly prolonged. Because the service life is prolonged, material consumption and maintenance cost of a user are greatly reduced, production cost is greatly reduced and meanwhile labor intensity of worker is greatly reduced.
Description
Technical field
The utility model relates to the backplate of smelting iron with on the sintering machine afterbody grate beam.
Background technology
Sintering machine is one of topmost technological equipment in iron and steel enterprise's ironmaking processes, and it makes Iron Ore Powder through being sintered into sintering feed.The production capacity of domestic sintering machine does not wait from producing hundreds of thousands ton to, 2,000,000 tons per year.The sintering machine afterbody is equipped with the blanking chamber, along with the next sintering feed of broken temperature between 800 to 900 ℃ of the rotation of single roll crusher in the blanking chamber.
A single roll crusher band 16,24,33 teeth do not wait.Along with the rotation of disintegrating machine, the tooth head part contacts with sintering feed and with its fragmentation.What bear sintering feed below is the grate beam, and the sintering feed of grate beam contact eight, 900 degree high temperature produces friction with sintering feed simultaneously, thereby rapid wearing.Often need to install a backplate on the outer surface of grate beam, as shown in Figure 1, the shape of backplate is as the channel-section steel of a back-off, and it is buckled in protection grate beam on the outer surface of grate beam.But present grate beam backplate average life only be between 2 to 4 months.Because service time is short, the frequent backplate that all will more renew, thereby just brought problems such as high material consumption, production efficiency is low, production cost is high, and labor strength is big.
The utility model content
The purpose of this utility model provides a kind of sintering machine with high-temperature wearable grate beam backplate, to solve existing grate beam backplate short problem service time.Described grate beam backplate comprises left riser 1, right riser 2 and level board 3, a left side riser 1 and right riser 2 are separately fixed on the lower edge of level board 3 both sides and make the three form the channel-section steel shape, the two ends of left side riser 1 respectively have a bolt hole 7, and bolt hole 7 runs through right riser 2, the both sides of level board 3 are evenly distributed with a plurality of slots 6, and alloy wear-resisting body 5 has been filled up in built-up welding in the slot 6.
In the use, the apical position of two sides of grate beam backplate is the fastest position of wearing and tearing, and therefore a lot of alloy wear-resisting bodies 5 are set at this position, thereby has improved the ability of heat-resistant antifriction.Service life is corresponding to extend to 6 to 12 months.Owing to the raising in service life, greatly reduce user's material consumption and maintenance cost, production cost reduces greatly, has also alleviated working strength of workers simultaneously greatly.
