Description
Technical field
The present invention relates to a kind of iron and steel or other industry to sample collection in irrigation canals and ditches and the sampling in place that manually should not be too close, particularly relate to one and be positioned at blast-melted ditch place to the sampler of high temperature iron liquid (slag).
Background technology
In recent years, the development of China's steel and iron industry is produced clean steel and is proposed requirements at the higher level, and as the primary raw material of steel-making, qualified hot metal composition up to standard directly affects a series of links such as follow-up steel-making, refining.Therefore, sampling and assay iron liquid (slag) safely, fast and accurately, just provides practical foundation for blast furnace, converter smelting process and batching system etc.
In blast furnace ironmaking process, because its design feature can not as the smelting furnaces such as converter, electric furnace or mixed iron blast, directly stove inside sampling after tilting, therefore its sample position is mainly positioned at iron tap channel or slag runner.What traditional sampling method generally adopted in decades is be poured in sample mould after steel spoon dips again, the mode of censorship after cooling.
In recent years, special survey rifle is adopted to have also been obtained widespread use in conjunction with the mode of various forms of sampler, sample is dipped this two step of same die casting and unites two into one by which, a loss can obtain for the multiple samples needed for different analyzing detecting method simultaneously, greatly reduce sampling number of times, but all need sampling personnel to close on the trough of high temperature, emit splash, scorch, the dangerous operation such as blast, there is sample position not fix simultaneously, insertion depth differs, operation has random significantly, dangerous and instability.
Summary of the invention
The object of the present invention is to provide a kind of sample position, insertion depth relatively fixing, the danger that personnel close on trough high-temperature service can be reduced, avoid the randomness of traditional sampling mode, instability etc., solve and arbitrarily shelve the blast-melted sampler that acquired hot sample easily causes the injury problems such as other people scald.
For achieving the above object, the concrete technical scheme of a kind of blast-melted sampler of the present invention is:
A kind of blast-melted sampler, comprise the fixed support being arranged on trough place, fixed support is provided with rotate and surveys rifle, rotate the end surveying rifle and be provided with sampler, rotate to rotate and survey rifle, dip the molten iron in trough by rotating the sampler surveying rifle end and molten iron sample is put in sample collection device.
The advantage of blast-melted sampler of the present invention is:
1) fixing sample position and sampling depth, make sample have more comparative, eliminate randomness and the instability of traditional sampling mode;
2) segmentation of rocking bar, lengthens, and juncture designs, and has both been convenient to partition assembling, saves idle and takes up an area, also can extend handling safety distance, improve the security of personnel;
3) specific combination of fixing rotating disk, rotary turnplate and rocking bar, makes to rotate and surveys rifle action and leave standstill reliably easy;
4) sampler mould is combined by special slide bar and chute form with survey rifle and dismantles, and efficiency is high;
5) package unit is compact, and structure is simple, with low cost, practical.
