The invention provides a manufacturing method for a low expansion alloy wide and thick plate. The manufacturing method comprises the steps of smelting target molten steel, molding and casting into a slab ingot, sawing the head and the tail of the ingot, planing, milling and scalping the surface of the ingot, heating the ingot to the temperature of 1100-1500 DEG C, then two-heat hot rolling the ingot, then keeping the temperature of 840 DEG C +/- 10 DEG C for one hour, water quenching, keeping the temperature of 315 DEG C +/- 10 DEG C for one hour, furnace cooling or air cooling, and after scraping edges, straightening, and surface treating, obtaining a low expansion alloy wide and thick plate finished product. According to the manufacturing method, the wide and thick plate finished product with satisfactory chemical components, satisfactory linear expansion coefficients and good surface quality can be obtained, and meanwhile manufacturing processes are reduced, a manufacturing cycle is shortened, a yield is improved, and cost is lowered.
