Problems solved by technology

[0004] At present, there are two types of universal rolling mills in the field of section steel short stress line (no archway) rolling mills: continuous plate type and POMINI red ring type. However, the characteristics of its own structure cannot be used as the best universal rolling mill suitable for rolling this anti-slip pattern I-type flat steel. rolling mill

Embodiment Construction

[0016] Fig. 1 is an embodiment disclosed by the present invention. A universal space self-positioning high-rigidity rolling mill with a nominal diameter of the horizontal roll of 300mm. The vertical roll system 3 is installed in the semi-closed archway to form a closed stress line loop of the rolling force of the vertical roll, which is convenient for quick roll change under the condition of meeting the rigidity requirements, and is suitable for workers to operate easily. Both the horizontal roll ring 14 and the vertical roll ring 20 adopt a combined structure to highlight the local roll rings in contact with the anti-skid I-type flat steel, and use high-alloy chilled cast iron materials to make the roll rings to improve high temperature resistance, high pressure and resistance. The working life of the mill is reduced and the number of roll changes is reduced.

[0017] This space self-positioning high-rigidity universal rolling mill realizes the best forming and rolling of an...

Abstract

The invention discloses a universal spatial self-angling stiff mill, relating to field of metallurgy machinery. It is characterized in that: vertical roll (3) is installed between the horizontal roll (1); cradle support (5), cross beam (6) and connecting column (7) are connected together through miter wedge (8,9) to form roll semi-closed memorial gateway; the worm gear screw thread auxiliary side pressing construction (10) installed in cross beam (6) is connected to roll box (12) containing vertical roll (13) to adjust the roll edge; the two sides of each worm gear screw thread auxiliary side pressing construction are equipped with spring equilibrium device (11), which is used to eliminate space on enclosed line by pressing roll box on side pressing bolt; the construction of horizontal and vertical roll are combined type; the roll ring made of high alloy hard cast iron material and contact with antiskid band steel I is projected out, which aims to increase the life length of fire and pressure and wear resistant roll. The invention is suitable for roll of antiskid band steel I antiskid band steel I production in multi-item-small-lot, and the accuracy and rate of finished products are increased.

Description

technical field [0001] The invention relates to the technical field of metallurgical machinery, in particular to a space self-aligning high-rigidity universal rolling mill. Background technique [0002] The characteristic of the universal rolling mill is that the axes of a pair of horizontal rolls and a pair of vertical rolls are co-located on the same plane, and each roll rolls the rolled piece simultaneously in the up and down and left and right directions. [0003] In China, the production of anti-slip I-shaped flat steel (section is I-shaped, one side is convex-concave anti-slip, and the other side is flat) products, currently mainly adopts the continuous rolling method of horizontal-vertical-horizontal rolling mills. However, due to the inherent characteristics of the required vertical roll mill for rolling anti-slip lines, it is difficult to roll into standardized anti-slip line I-shaped flat steels, and the reject rate reaches 20%, seriously reducing the yield of prod...
