Technical field

The invention belongs to the technical fields of converter installation dimensional measurement, and in particular to one kind is for measuring converter mouth size Measuring device.

Background technique

The flue gas and clinker generated in pneumatic steelmaking smelting process is poured out from converter mouth, while fire door is also to smelt Process oxygen lance lifting and sublance go up and down unique channel, keep suitable fire door size to be to ensure that converter installation is stablized and smelt, is raw Produce the precondition of direct motion.Under the conditions of the molten iron and raw material of current complexity, converter steelmaking process is also easy to produce metal and melts Slag splash, it is additional to topple over clinker, converter mouth repeatability dry slag is caused, fire door is caused to reduce, it, can be tight if clearing up fire door not in time Ghost image rings converter smelting, or even is forced blowing out processing, and strong influence normally produces.Therefore, the size of fire door size is to influence One of an important factor for converter smelting.

Measurement fire door dry slag thickness at present, predominantly estimation mode, main process include: to shake converter body forward To 90 degree, fire-screen door is opened, using estimation mode, estimates fire door dry slag thickness；Appraisal is subtracted with the original size of converter mouth Fire door dry slag thickness obtains practical converter mouth size.According to the practical converter mouth size come artificially judge whether into Row cleaning converter mouth dry slag operation.But in range estimation converter mouth dimension process, first is that due to converter in-furnace temperature pole Height reaches 1000 degrees Celsius or more, and by the outside radiations heat energy of fire door, heat radiation is extremely strong, and erect-position is excessively close then easily to generate scald, Security risk is brought to operator；Therefore, it is necessary to operators to be avoided using farther away erect-position, and general erect-position is 10 Meter or more, larger distance is easy to generate relatively large deviation to judgement；Second is that existing converter mouth is having a size of 2.2 meters, it is suitable to turn Furnace fire door is having a size of 2 meters, and under remote range estimation, fire door is influenced by the high temperature coloured smoke and dry slag that generate in furnace, to master Sight judges that fire door size is also easy to produce relatively large deviation.If clearing up, fire door dry slag is too early, wastes the valuable production time, reduces life Produce efficiency；If clearing up fire door dry slag too late, the smooth of production will affect.

Summary of the invention

It is an object of the present invention to solve existing measurement method, there are drawbacks described above, and the invention proposes a kind of use In the measuring device of measurement converter mouth size, which is independent integrated movable T-type structure, is welded using being fully welded It connects, and is placed on bracket；The structure of the measuring device is simple, easy to make, and using effect is good.Converter mouth size can be achieved Standardized administration, to operator provide it is intuitive and convenient measure method, can avoid naked eyes and judge bring relatively large deviation, in time It determines that fire door clears up opportunity according to measurement situation, normally produces and provide safeguard for converter.

To achieve the goals above, the present invention provides a kind of for measuring the measuring device of converter mouth size, the survey Measuring device includes:

Bracket and measuring scale；Bracket is fixed on platform, and measuring scale is fixed on bracket, and measuring scale and bracket are in just Friendship is disposed vertically.

One of as an improvement of the above technical solution, the measuring scale is removable or revolving T-shaped structure, using full Welding manner is welded, measuring scale is fixed on bracket；Measuring scale can be on bracket freely close to or far from fire door.

One of as an improvement of the above technical solution, the measuring scale includes: handle portion and measurement portion；Handle portion and measurement The perpendicular relationship in portion；

Handle portion is vertical section, and measurement portion is transversely and horizontally section；Handle portion and measurement portion are all the steel that diameter is 10-15mm Pipe；The length of handle portion 7 is 3.5-4m；The length of measurement portion 8 is 2m ± 2cm.

One of as an improvement of the above technical solution, by way of being fully welded welding, one end of handle portion is fixed on survey The middle part in amount portion, i.e. handle portion are vertical with measurement portion midpoint to be connect；Measurement portion is equipped with scale；Its precision is each scale It is separated by 10cm between adjacent scale.

One of as an improvement of the above technical solution, the bracket is the A-frame for being fully welded welding using angle steel and being formed, It can be moved freely on platform, be used to support measuring scale.

One of as an improvement of the above technical solution, the bracket includes the tripod-shaped structure that 3 angle steel surround, angle Steel pattern number is L63-70.

Bracket is placed on platform, the center of face fire door is moved to, provides support for measuring scale；By Converter Body shakes forward to 90 degree, is convenient for measuring ruler measurement converter mouth size；One end of the handle portion of measuring scale is weldingly fixed on The handle portion of measuring scale is placed on bracket by being fully welded welding manner, measurement portion is directed at Converter by the middle part of measurement portion Mouthful, the scale being equipped with according to measurement portion can quickly obtain the size of converter mouth；Centered on measuring scale, by fire-screen door to It is mobile close to the direction of measuring scale, reduce heat radiation.

The present invention has the advantages that

The structure of measuring device of the invention is simple, easy to make, using effect it is good, it can be achieved that converter mouth size rule Model management provides intuitive, convenient and fast measurement method to operator, can avoid naked eyes and judges bring relatively large deviation, timely root It determines that fire door clears up opportunity according to measurement situation, normally produces and provide safeguard for converter.
