[0024] It should be noted that the cold-rolled steel strip is a kind of steel produced by cold rolling process, which has high dimensional accuracy, good surface quality and excellent mechanical properties. In the production process, improving the tensile strength of the cold-rolled steel strip is an important means to improve its mechanical properties and application range. The internal stress generated during cold rolling can be eliminated by heat treatment to restore the plasticity and toughness of the material, while improving the tensile strength. First, the cold-rolled steel strip enters the heating bin 1 from the rotating door 2 on the left side. The conveying roller on the rotating door 2 makes the cold-rolled steel strip conveying more convenient. The heating pipe 4 heats the cold-rolled steel strip. During the heat treatment process, dust and slag and other impurities will be generated on the surface of the cold-rolled steel strip, which will affect the quality of the finished product. The surface of the cold-rolled steel strip needs to be scraped. The cold-rolled steel strip after heat treatment is transported out from the rotating door 2 on the left side. According to the thickness of the cold-rolled steel strip, rotate the knob 67 to make the gear rotate, and then drive the rack to move under the guidance of the second guide 65, thereby driving the first scraper 61 to move under the guidance of the first guide 64 to adjust the relative distance between the first scraper 61 and the second scraper 610. The first scraper 61 scrapes the upper part of the cold-rolled steel strip. Under the action of the spring 63, the scraper adjusts to the surface of the cold-rolled steel strip, thereby better scraping the impurities on the upper surface of the cold-rolled steel strip. At the same time, the second scraper 610 scrapes the lower part of the cold-rolled steel strip. The obtuse angle structure on both sides of the first scraper 61 facilitates the gathering of impurities on the first scraper 61. The through holes are opened on both sides of the first scraper 61 to facilitate the falling of impurities from the first scraper 61 to the collection frame 69. When the impurities accumulate, the locking member 3 is actuated to make the rotating door 2 out of the locked state. Then rotate the rotating door 2 to make the inside of the heating bin 1 in an unfolded state. Then rotate the dial block on the mounting frame 68, and use the handle to pull the collection frame 69 outwards, thereby quickly cleaning the impurities in the collection frame 69.

The first mounting plate 71 and the adjacent second mounting plate 73 are connected with the fan 72.

[0027] It should be noted that relying on a single heating pipe 4 to heat the cold-rolled steel strip has limited effect. The fan 72 can accelerate the air circulation in the heating bin 1, thereby quickly delivering heat to the heating bin 1, which can accelerate the heating speed of the cold-rolled steel strip, thereby improving the heating effect and improving the efficiency of improving the tensile strength of the cold-rolled steel strip.
