The invention relates to a production method of a low-creep energy-saving and environment-friendly refractory material used for a carbon baking furnace. The production method comprises the step: preparing the refractory material from components in percentage by weight through a production process flow. The production method is characterized in that the refractory material comprises the following components in percentage by weight: 70-90% of MgO, 5-10% of Al2O3, 0-8% of magnesia-alumina spinel, 2-5% of Fe2O3, 1-3% of CaO, 0-10% of SiC, 1-5% of TiO2 and 1-3% of SiO2; the production process flow comprise the following steps: dosing, material mixing, molding, drying and sintering. Therefore, the production method has the advantages that the thermal conductivity is high, the stability is high, the corrosion resistance is high, the production method is energy-saving and environment-friendly, the service life is prolonged, and the abrasion resistance is high. 本发明涉及种炭素焙烧炉用低蠕变节能环保耐火材料的制作方法，它包括组成与重量百分比含量和制作工艺流程，其特征在于：耐
