Description
Technical field
The present invention relates to a kind of device that is used for dehydration of metallurgy industry belt steel surface and the coating of belt steel surface liquid anticorrosive paint.
Background technology
At present, on metallurgy industry cold rolled strip steel production line, the band steel is after cooling off through watch-quench tank or cleaning, and the residual moisture content of belt steel surface mainly relies on rubber roll to extract, and the coated of belt steel surface anti-corrosion material also is to rely on rubber roll to push to be stained with to be coated with.The coated effect of the dehydration of belt steel surface and anti-corrosion material depends on the surface quality of rubber roll.Because the resistance when being subjected to the influence of roll surface distortion that its rubber roll is rotated after the contact of rubber roll roll surface is bigger, linear velocity when rubber roll rotates is slow than strip speed, coating particles that the rubber roll surface embeds and impurity easily produce belt steel surface and scratch, thereby have a strong impact on surface quality of products.The band steel must carry out the roll change operation when variations such as specification such as width, thickness in a single day occurring, and rubber roll spare parts consumption amount and workman's amount of labour are all very big, thereby have increased the production cost of enterprise.And owing to be subjected to rubber roll roll surface distortion quantitative limitation, the thick band steel especially limit portion moisture content of the above big band steel of 1.2mm can not be squeezed out.The impurity that existing rubber roll dewatering type can not stick belt steel surface and stick not firm coating particle and remove produces bigger influence to the subsequent handling of unit.In addition, making the rubber roll surfacing is rubber, and the use of rubber also easily causes environmental pollution.
Summary of the invention
Extract residual moisture content of belt steel surface and coated belt steel surface anti-corrosion material above shortcomings in order to overcome the existing rubber roll that relies on, technical problem to be solved by this invention provides a kind of band steel dehydrating and coating device that does not have the machinery contact.
The technical solution adopted for the present invention to solve the technical problems is: this band steel dehydrating and coating device, in symmetric arrangement about band steel transfer position the winding-up beam that is communicated with source of the gas is arranged, the front end of winding-up beam is provided with two cutter lips that extend along the width of band steel near band steel transfer position place, is provided with the gap that forms nozzle between two cutter lips.
Further be, be connected with control system and detection system by pipeline between winding-up beam and the source of the gas, control system is controlled the gas pressure at nozzle place by detection system.
Further be, the winding-up beam is arranged on the adjusting device, and adjusting device is controlled by control system.
Further be the rotation adjuster of adjusting device for the winding-up beam is rotated along its pivot.
The invention has the beneficial effects as follows: because the kinetic energy that this device utilizes pressure-air to have, moisture content, the impurity that sticks that belt steel surface is adhered to and adhere to that not firm coating particle is peeled off or carry out coated to the liquid anticorrosive paint of belt steel surface, therefore do not have machinery to contact with the band steel, thereby realize contactless dehydration and coated.This device not only can be not with the restriction of steel specifications vary, also can under the situation of not having the machinery contact, slough the moisture content that belt steel surface adheres to, and can remove, or the nonmetal anticorrosive paint of belt steel surface there is not the even coating of machinery contact with being attached on the impurity of belt steel surface and sticking not firm coating particle.Realize not having machinery contact dehydration or coated technology and the non-maintaining function of equipment fully, reduced production cost and workman's amount of labour, improved production efficiency.The influence that this device does not change with steel specification (thickness, width) can be implemented in line automation control easily, can be widely used in dehydration of metallurgy industry belt steel surface and the coating of belt steel surface liquid anticorrosive paint.
