Dash chain apparatus before the above-mentioned hot-continuous-rolling strip steel production line roughing edger roll; Said link plate is a polylith; Order is arranged and is installed on the link plate gyroaxis; Link plate top is the circular arc plate, and the excircle of the radian of circular arc plate and link plate gyroaxis is complementary, and the madial wall of circular arc plate is looped around on the top circumference of link plate gyroaxis.
Dash chain apparatus before the above-mentioned hot-continuous-rolling strip steel production line roughing edger roll; Said dash chain is made up of the multilayer chain; Arranged along the length direction linear sequence of link plate by many chains for every layer, front and back are arranged in parallel between each layer, and the bottom of dash chain falls to and is lower than roller-way absolute altitude 5～10mm.
Dash chain apparatus before the above-mentioned hot-continuous-rolling strip steel production line roughing edger roll; Said every chain is connected by the round-link chain of a plurality of Φ 20～Φ 30mm; The dash chain is 3～5 layers; Have two Φ 18mm round steel laterally from the round-link chain of each bar chain, to pass respectively every layer of chain upper and lower, the length of round steel is identical with link plate length.
The usefulness of the utility model is:
Dash chain link plate of the utility model and dash chain are installed on the link plate gyroaxis; Swing back and forth in the time of can passing in and out mill milling with slab; Can stop cooling water and dephosphorization water backwash on the roughing mill and trickle along slab; Guarantee positive normal open plate and rolling temperature, stablized the template of middle blank, improved the product quality quality; Greatly reduce probability simultaneously to the damage of roughing equipment.The utility model is simple in structure, be easy to change, and can satisfy the production demand.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model;
Fig. 2 is the mounting structure sketch map of link plate;
Fig. 3 is the mounting structure sketch map of dash chain.
Mark is following among the figure: first road interception water 1, second road interception water 2, pony roughing mill roller-way 3, down side guide plate 4, dash chain 5, link plate 6, link plate gyroaxis 7, support 8, set bolt 9, edger roll memorial archway framework 10, slab 11, edger roll machine afer bay roller 12, edger roll machine forebay roller 13, round steel 14, bearing pin 15, square hole 16.
The specific embodiment
The utility model is made up of support 8, link plate gyroaxis 7, link plate 6 and dash chain 5.
