The invention provides an ingot mould used for casting an iron alloy and a casting method thereof. The casting method comprises the following steps of: mounting an ingot mould set provided with an iron runner into a stepped sequentially-cast arrangement structure in stepped fall positions, arranging the ingot moulds, assembling, demoulding and lifting iron, pouring molten iron, fetching the iron and demoulding, quenching with water and finishing to cast the iron alloy; when the temperature of an iron block is reduced to 700-1000 DEG C, fetching the iron, and quenching an alloy iron block at high temperature with water, thus internal metallographic structure is converted into crisp thick longitudinal columnar crystal and massive micro cracks are produced on the surface, and the crushing difficulty is greatly reduced. By adopting the ingot mould and the casting method provided by the invention, the production conditions can be obviously improved, the labour intensity is alleviated, the crushing processing effic
